My five questions on the computing world

We have supercomputers. We have computer simulations. Some simulations can be quite accurate. Now I have three questions to ask:

  1. Is it possible that algorithms and computational power can grow to a point that a physical world can be simulated continuously?
  2. Is it possible that a sentimental entity can be simulated in such a system, if it exists?
  3. If such a simulation can be achieved, can we consider the machine simulating the entity a sentimental machine?
  4. Is it possible for the entity within the emulation tell if it is emulated?
  5. Is it possible that the world we currently exist in emulated? If so can we detect the emulation?

Review: Bridge to Terabithia

Recently I came to the film, Bridge to Terabithia. The 2007 film, I know, after 7 years I finally came through it.

Being a Disney/Walden production given the trailer (which I just heard of, not actually seen,) it is believed to be something as much a magic show as Narnia but, well, it is definitely not.

GNU on OS X

I am a OS X user, and I am also a Linux user. OS X packs FreeBSD user land, Linux packs GNU user land. Somehow I managed to like OS X, but also GNU user land.

That is why I am always trying to replace my OS X FreeBSD user land with GNU equivalents. That will involve some heavy-duty compiling and checking. Tiring, but rewarding as my scripts can work on both systems.

One missing piece I tried to port but never succeed is Ubuntu’s bash-completion package which is makes bash super easy to use.

Raspbian Server Edition forks: NK and AC

I have a thing of running my Raspberry Pi headless, using Raspbian Server Edition. Current versions of Raspbian Server Edition is sort of old now, though.

I am preparing two forks of Raspbian Server Edition, both based on upstream version 2.5:

  • RSE 2.5NK: Based on RSE 2.5, latest bootloader, kernel is from rpi-update.
  • RSE 2.5AC: Based on RSE 2.5, latest bootloader, kernel have Wolfson Audio Card support.
  • RSE 2.5NK+: Based on NK, added command-line GPIO utilities, LAMP stack and mod_suexec for apache. Intended to be used as a home automation hub.
  • RSE 2.5AC+: Like NK+, but based on AC kernel. Intended to be used as a DLNA/AirPlay target or multipurpose guitar effect stompbox.

Stuff is still being assembled, and I will publish torrents and download links once it is finished.

China Telecom EPON device, IPTV and TR069

After reading Wesley’s post about their problematic, data stealing router, I want to rant about mine.

In the neighbourhood I am living in, the only ISP is China Telecom.

For those who want a broadband connection, Telecom’s standard issue CPE is a combined EPON/Router device.  The device establishes EPON and PPPoE connection for you, have built-in DHCP server and Wi-Fi access point, and seems to be a good all-in-one CPE.

Review: Austin & Ally: “Future Sounds & Festival Songs”

Recently I started on that TV show. I am a 21-year-old but when I am stressed out I still, occasionally, watch Disney Channel shows.

This particular episode, however, caught my notice. It is about Austin finding out about a songwriting machine (or algorithm) that takes a few notes as its input, and spits out a whole pop-ish song.
